Abstract

Cardiac pacing is the only effective therapy for patients with symptomatic brady-arrhythmia. Traditional right ventricular apical pacing causes electrical and mechanical dyssynchrony resulting in left ventricular dysfunction, recurrent heart failure and atrial arrhythmias. Physiological pacing activates the normal cardiac conduction thereby providing synchronized contraction of ventricles. Though His bundle pacing (HBP) acts as an ideal physiological pacing modality, it is technically challenging and associated with troubleshooting issues during follow up. Left bundle branch pacing (LBBP) has been suggested as an effective alternative to overcome the limitations of HBP as it provides low and stable pacing threshold, lead stability and correction of distal conduction system disease. This paper will focus on the implantation technique, troubleshooting, clinical implications and a review of published literature of LBBP
